DEVICE FOR TESTING OF INDUCTIVE ELECTRIC METERS Russian patent published in 2015 - IPC G01R11/24 

Abstract RU 2569178 C1

FIELD: electricity.

SUBSTANCE: invention claims the device for testing inductive electric meters designed with bridge circuit and consisting of the first and second circuits comprised of in-series storage capacitor and power transistor and coupled in parallel to phase and neutral lead downwards electric meters, at that in the first circuit storage capacitor is connected to the phase lead, while in the second circuit power transistor is connected to the phase lead, and in the second circuit power transistor is connected to the phase lead, between midpoints of both circuits there is thyristor, and the above device is differentiated by in-series connection of choke to the thyristor, and inductance of this choke together with storage capacitors of the above circuits switched on at open thyristor forms in-series resonant circuit adjusted to double frequency of the mains.

EFFECT: simplification of the device designed with bridge circuit without high-frequency current splitting for charge of storage capacitors.
